Circuitry

Description

FSA4157 and FSA4157A are high performance Single

Pole/Double Throw (SPDT) analog switches. Both

devices feature ultra low RON of 1.15Ω maximum at

4.5V VCC and operates over the wide VCC range of

1.65V to 5.5V for FSA4157, and 2.7V to 5.5V for

FSA4157A. The device is fabricated with sub-micron

CMOS technology to achieve fast switching speeds and

is designed for break-before-make operation. The

select input is TTL level compatible.

The FSA4157A features very low quiescent current

even when the control voltage is lower than the VCC

supply. This feature services the mobile handset

applications very well allowing for the direct interface

with baseband processor general purpose I/Os.

Technology Description

The Fairchild Switch family derives from and embodies

Fairchild’s proven switch technology used for several

years in its 74LVXL384 (FST3384) bus switch product.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device

reliability. The absolute maximum ratings are stress ratings only.

3. Measured by the voltage drop between the A and B pins at the indicated current through the switch. On

resistance is determined by the lower of the voltage on the two (A or B ports).

4. ΔRON = RON max – RON min measured at identical VCC, temperature, and voltage.

5. Flatness is defined as the difference between the maximum and minimum value of on resistance over the

specified range of conditions.
